IMPROVEMENT IN GRAIN-BINDING MACHINES.

Specification fawning part of Letters Patent 1V 0. 31,526, datedFebruary 26, 1861.

To all whom it may concern Be it known that I, W. W. BURSON, of YatesCity, in the county of Knox, State of Illinois, have invented a new anduseful Machine for Binding Grain and I do hereby declare that thefollowing is a'full and exact description of the same, reference beingbad to the accompanying drawings, forming part of this specification, inthe several figures of which similar letters of reference denote thesame part.

Figure 1 is a side elevation, the arm A A", full lines, being inposition for receiving the gavel, the dotted lines showing its positionwhile the band is being fastened. Fig. 2 is a front elevation, the arm AA and platform K being removed. Fig. 3 is a perspective view, the partsU and H being removed. Fig. 4 is a plan view of the grain-platform K,the twisting-jaws c o, and device for cutting and holding the wire. Fig.5 shows the cam-groove of the cog-wheel at. Fig. 6 shows lever y. Fig. 7shows lever s. Fig. 8 shows receptacle h.

My invention has reference to the binding of grain with wire upon theplatform of any reaping-machine; and consists of certain combination ofdevices,hereinafter to be described.

In the drawing, Fig. 1, R It supports the arm A by bearing D D. Theplatform K receives the grain preparatory to binding, and is made withan opening, M, which the arm A traverses in passing the wire under andaround the gavel. Said opening allows the rubbish to fall through, whichmight otherwise be carried by arm A into the twisting apparatus.

The spikes d d on the sides of the opening M prevent the arm from takingthe straw into the twisting device, the strips 6 0 partially coveringsaid opening, and assisting in the same result.

The guide a, Fig. 3, insures the coming of the arm A to the properposition for fastenin g the wire around the gavel.

The arm A A is jointed at B. The pitman G attaches the fore arm A at E.The pinion O, secured upon A, meshes in segments 1? P, which arestationary upon the uprights R R. The rack S upon the rear portion ofpitman 0 meshes in pinion 0.

The cord WV, attaching the fore arm A at cl, passes through eyelet inslide J, over pulley X, and fastens to the weight-ball V.

The crank P upon shaft f rotates wheel 00, which, meshing in pinion i onshaft 0, rotates the twisting-jaws c c, the jaw 0 being hinged to c,permanently secured upon shaft 0.

The twisting-jaws c c are opened by the spur n of lever y, Fig. 6,moving against the projection on the rear portion of 0. They are closedby the rotation of the shaft 0, which brings 0' within the concave H.The front end of lever 3 being also concave, closing upon them, holdsthem closed while the rotation twists the wire.

Lever S, Fig. 7, is corrugated on its front end, its lower surfacehaving the teeth m, and its upper surface being shearedged.

The receptacle h, Fig. 8, matching the face of levers, Figs. 7 and 8,has its upper surface shear-edged, and the lip t insures the propermatching of the cuttingedges.

The spool N, Fig. 2, holding the wire for binding the gavels, is securedupon the up right 1t, under spring-catch L, which position is necessaryto enable the operator to change his hand readily from the spool to thecrank, after drawing the band tightly around the gavel.

The offset q and elevation 2, Fig. 1, near the end of fore arm A, insurethe placing of the wire in the twisting-jaws c c, assisted by guard It.

In operating, this grain-binder is placed upon the platform of anyreaping-machine, where it would be most convenient for the raker toplace the gavel upon the platform It.

The operator passes the end of wire from spoolN through loops 1 I, andthe hole in the end of A, when the arm is brought down to its positionof rest, the twisting devices being in the position of rest, as shown inFig. 3.

With his left hand the operator takes hold of the crankP and turns tothe left, simultaneously pressing down the spring-catch L. Onerevolution securely fastens the end of the wire. The operator thenraises arm A A by handle F, which rotates the pinion O, meshing insegments P P, acting upon rack S to draw pitman 0, attached to A at E,thereby extending the fore arm A ,and stretching the wire from thetwisting device, as shown in Fig. 1.

The gavel being placed upon platform K, the arm A is pushed down at thesame time the spool N is reversed, thereby drawing the wire tightlyaround the gavel. The tighteningcord W, by this movement, being thrownaround the "gavel, the weight V and slide J assist in compressing it.The crank 11, being turned to the left, rotates the twisting-jaws. Therear portion of lever y, moving in groove w of wheel 00, holds thetwisting-jaws securely closed until arriving at cam T, which throws therear end toward the center of the wheel, and the spur n outward, andtherewith jaw 0. At the same time the rear end of lever s, moving ingroove u, behind and underneath the rear portion of lever 3 holds theend of wire until the cam r releases it. When the wire, running from thetwisting-jaws through the eyelet of A, is brought into position, thelever 8 closing against receptacle In, it is severed by the shear-edgesof said lever and receptacle, while the corrugated surfaces of the saidlever and receptacle securely hold the spool end of the wire, and thecompleted revolution of crank 10 securely fastens the now severed wirearound the gavel.

The crank 19, resting in spring-catch L, shows the twisting device inproper position for the armA to be again raised, when the sheaf isremoved and the machine is in readiness for another gavel.

What I claim as my invention, and desire to secure by Letters Patent,is'

1. The combination of the jointed armAA, pitman O, rack S, segments P P,and pinion 0, operating substantially as and for the purpose set forth.

2. The combination of the cord W, weight V, slide J, and arm A A,substantially as described.

3. The platform K, constructed with opening M, said opening providedwith the spikes d d d, and guide a, substantially as described.

4. The hinged jaws 0 c, shield or guard k, and the concave H, operatingsubstantially as set forth.

5. The combination of lever s and receptacle h, constructedsubstantially as described.

6. The lever y, with spur n, operating for the purpose of opening andclosing the twistingjaw c c, as described.
